Legal effect
None. A surveillance count, not an order.
What this establishes
- A year-to-date count of 3,294 confirmed cases as of the 10 September 2026 update.
What this does not establish
- A count for any later week.
- Any change to the childhood immunization schedule, which remains governed by the court stay in AAP v. Kennedy.
Why it matters
Measles counts are the clearest available measure of how immunization coverage is actually holding, independent of the schedule dispute.
